Abstract

"PROCESSO PARA MATAR INSETOS VOADORES, E, DISPOSITIVO DE BORRIFAMENTO". Um processo para matar insetos voadores, cujo processo compreende borrifar no ar no qual os insetos estão voando gotículas líquidas de uma composição inseticida, sendo impressa uma carga unipolar a ditas gotículas líquidas por meio de carregamento de dupla camada e separação de carga durante o borrifamento, a carga unipolar estando em um nível tal que as ditas gotículas tem uma relação de carga para massa de no mínimo +/- 1 x 10^ -4^ C/kg. Um dispositivo de borrifamento de aerossol que é capaz de imprimir uma carga unipolar por carregamento de dupla camada e separação de carga às gotículas líquidas de uma composição borrifada a partir dele, tem uma cabeça de borrifamento na forma de um inserto em um atuador, a cabeça de borrifamento que tem um furo através do qual líquido é expelido tem uma saída, preferivelmente com uma periferia sinuosa que tem uma relação L/a de no mínimo 8, onde <MU>L<MV> é o comprimento da periferia que define a saída do furo em mm, e <MU>a<MV> é <MU>a<MV> área da seção transversal da saída do furo em mm^ 2^ e o aparelho sendo construído de tal modo que as gotículas são expelidas da cabeça de borrifamento a uma relação de vazão de no mínimo 0,5 gramas por segundo, e tem uma relação de carga para massa de no mínimo +/- 1 X 10^ -4^ C/kg."PROCESS TO KILL FLYING INSECTS, AND, BORRIFYING DEVICE". A process to kill flying insects, the process of which sprays in the air in which insects are flying liquid droplets of an insecticidal composition, being printed a unipolar charge to said liquid droplets by means of double layer loading and charge separation during spraying, the unipolar charge being at a level such that said droplets have a charge to mass ratio of at least +/- 1 x 10 ^ -4 ^ C / kg. An aerosol spray device that is capable of printing a unipolar charge by double layer loading and charge separation to the liquid droplets of a composition sprayed from it, has a spray head in the form of an insert in an actuator, the head sprinkler that has a hole through which liquid is expelled has an outlet, preferably with a winding periphery that has an L / a ratio of at least 8, where <MU> L <MV> is the length of the periphery that defines the outlet of the hole in mm, and <MU> to <MV> is <MU> the <MV> cross-sectional area of the hole outlet in mm ^ 2 ^ and the apparatus being constructed in such a way that the droplets are expelled from the spraying at a flow rate of at least 0.5 grams per second, and has a charge to mass ratio of at least +/- 1 X 10 ^ -4 ^ C / kg.
